SVETLANKA909090 [29]3 years ago
5 0

Answer:

x = 93.4° ( to 1 dec. place )

Step-by-step explanation:

Given

\sqrt{34} cos(x - 46.7)° = 4 ( divide both sides by \sqrt{34} )

cos(x - 46.7)° = \frac{4}{\sqrt{34} }, thus

x - 46.7 = cos^{-1}( \frac{4}{\sqrt{34} } ) ≈ 46.7° ( add 46.7° to both sides )

x ≈ 93.4°

Nazerhy deposits $8,000 in a certificate of deposit. The annual interest rate is 6%, and the interest will be compounded monthly
Likurg_2 [28]

Answer:

A=\$14,555.17

Step-by-step explanation:

we know that    

The compound interest formula is equal to  

A=P(1+\frac{r}{n})^{nt}  

where  

A is the Final Investment Value  

P is the Principal amount of money to be invested  

r is the rate of interest  in decimal

t is Number of Time Periods  

n is the number of times interest is compounded per year

in this problem we have  

t=10\ years\\ P=\$8,000\\ r=6\%=6/100=0.06\\n=12  

substitute in the formula above

A=8,000(1+\frac{0.06}{12})^{12*10}  

A=8,000(1.005)^{120}  

A=\$14,555.17

Round number to nearest hundred 1,427 as 1,420. 68,136 as 68,130. 271,308 as 271,300. 7,593,656 as 7,594,000 right?
xenn [34]
Normally to round a number to the nearest hundred you want to go to the hundreds column for example:
1427
1...thousand, 4...hundred, 2...tenth, and 7... ones so this one would be 1400
68136=68100 and so on.... hope this helps
